Photometric observations of emission B-stars in the southern Milky Way
In order to study the distribution of Be stars and their correlation tothe local spiral structure of the Galaxy photoelectric UBV photometrywas carried out for a total of 488 Be stars located in the southernMilky Way between galactic longitudes 315 and 45 deg. UBV magnitudes arepresented for these stars.

Photometric reductions and the lightcurve of (51) NEMAUSA
The light curve of the minor planet (51) Nemausa is derived on the basisof 1779 photoelectric (B and V) observations and a photometric reductionusing a rigorous least squares method. Separate light curves are givenfor the B and V observations, respectively. An absolute B-V magnitudefor (51) Nemusa of 0.787 + or - 0.004 mag was estimated. A detaileddescription of the least squares method is presented.
